Your Kohler Electronic Valve
Your new Kohler Exposed Electronic Urinal Valve is precision
engineered and constructed of premium quality materials to provide
trouble-free operation even under the hardest water conditions.
1025497-5-B 2 Kohler Co.

Your Kohler Electronic Valve (cont.)
Design Features
The valve is designed specifically for use with 3/4″(1.9 cm) top spud
washout urinals as offered by Kohler Company and others. It is not
designed for use with blowout or siphon jet flushing systems.
The valve is supplied with factory preset timing values. No
programming or adjustment is required.
Depending upon use, the lithium battery can be expected to last for
two or three years before replacement is required.
Flush Operations
NOTE: The pre-flush feature can be disabled if desired using a
magnetic key. For more information, call Kohler Customer Service at
1-800-4-KOHLER from 7 AM to 6 PM Central Standard Time or
order online 24 hours at www.kohler.com.
The Exposed Electronic Urinal Valve provides the following flushing
operations:
An automatic pre-flush operation: Shortly after the individual
approaches the urinal, the valve provides a preliminary flush that
lasts just a few seconds.
An automatic main flush operation: Shortly after the individual
departs the urinal, the valve provides a main flush that lasts for
several seconds.
An automatic 24-hour flush operation: Once every 24-hours, the
valve produces a full flush.
Vandalism Protection
Your Kohler urinal valve has a vandal resistant feature. If the sensor
detects a continuous presence for 180 seconds, it enters the vandal
resistant state. In this state, it immediately performs a normal flush but
does not flush again until the sensor does not detect a presence. The
valve returns to the normal state if there is no target detected for more
than two seconds. When it goes to normal state, it performs a normal
flush.
Low Battery Indication
The lithium battery can be expected to last for two or three years
before replacement is required. When the battery reaches a certain
point in its lifetime, the valve announces the low battery condition by
Kohler Co. 3 1025497-5-B

Your Kohler Electronic Valve (cont.)
beeping whenever a user is in range. The battery is easily replaced as
described in the section ″Replace the Battery″in this guide.
Replacement batteries can be purchased from drugstores or other stores
stocking batteries used for photography. The battery is a 6.0 volt 1300
mAh Lithium battery with model numbers of 2CR5, DL245, EL2CR5,
KL2CR5, or 2CR5M.
Failed DC Sensor Indication
The Exposed Electronic Urinal Valve also provides a warning
indication when the unit determines that the DC sensor has failed. If
the DC sensor has failed, the unit beeps once every five minutes. The
DC sensor is easily replaced as described below. Refer to the service
parts section for the part number.
Seasonal Use
The Exposed Electronic Urinal Valve is not designed for operation in
freezing conditions. If freezing conditions are expected, isolate and
drain the urinal valve along with whatever other winterization steps
are taken for the facility.
Mobile Use
The Exposed Electronic Urinal Valve is not designed for use in moving
environments such as boats.
Care and Cleaning
Like anything of lasting quality, Kohler valves and fittings require a
certain amount of periodic care to preserve their lustrous finish. Clean
your new Kohler valve and fittings with a soft sponge and a mild
soap. Rinse thoroughly with warm water and dry with a clean, soft
cloth. The ideal cleaning technique is to blot dry any water from metal
surfaces. Allowing water to evaporate on metal will form water
deposits. It is important to use a dabbing action to dry metal, not an
abrasive or rubbing action.
Never use cleaners containing abrasive cleansers, ammonia, bleach,
acids, or other corrosive chemicals that can damage the finish. Do not
use dishwashing detergent or other cleaners with a pH outside of the
range of 6 to 9. By taking the time to dry your faucet often, soap and
water deposits can be prevented.
Clean the DC Sensor frequently for faultless operation.
If your chrome or Vibrant
®
color/finish faucet gets excessively dirty,

consider using the following cleaners: Windex

Original, Fantastik

All
Purpose, Spic and Span Pine Liquid, or Mr. Clean Springtime Fresh
Scent. For solid color faucets and fittings, consider using these
cleaners: Fantastik

warranty obligations.
